FAQ
Q1: How can I confirm compatibility without connector size?
Check your original adapter for 12V output and 5.5mm barrel-type DC connector. If physical plug matches and current requirement is 1.25A or lower, it is likely compatible.
Q2: Can this replace higher current adapters?
It can replace adapters with equal or lower current rating, but not devices requiring more than 1.25A.
Q3: Is this suitable for continuous operation?
Yes, it is designed for stable 24/7 operation in low-power networking and embedded applications.
Q4: Can it be used for CCTV systems?
Yes, for low-power single-camera or small surveillance setups that match 12V input requirements.
